In-Band Firmware Update

[Patrick Venture]

In an effort to do the OEM IPMI firmware update as full open source
and to enable testing more thoroughly, I'm writing it anew and staging
the patches upstream.
https://gerrit.openbmc-project.xyz/#/c/openbmc/phosphor-ipmi-flash/+/11772/
is the current top of the stack of patches, but that'll change a bit
this week as I implement more of the design.

If you're very interested, and not on the patches, please let me know
and I will add you to future ones.  That said, other than next week,
when I'll be out-of-office, I'm hoping to keep the patches going in a
brisk pace, so rapid feedback is appreciated.  Once the block-transfer
interface portion is finished, I'll push up the host-side tool (which
I also get to write anew).
